Design and Simulation of Variable Speed Constant Frequency Brushless Doubly Fed Wind Power Generator
Brushless Doubly-fed Machine (BDFM) is a new inverter-driven induction motor, and it has broad prospects in wind power generation. This paper analyses the structure and VSCF electricity generating principle of a cascade Brushless Doubly fed Wind Power Generator, deduces the BDFG’s mathematical model, The variable structure control (VSC) was used to the active and reactive power decoupling control of the BDFM, analysis the relation of electromagnetism and energy balance .Finally, simulation and analysis of the whole system and control strategy are carried through in matlab/simulink soft. According to these results, the correct of parameters and simulation model for BDFM is proved.
